NECK- YOKE.

SPECIFICATION forming part of Letters Patent No. 364,266, dated June 7,1887.

Application filed January 27,1887. Serial No. 225,644. (No model.)

To all whom it may concern.-

Be it known that I, HENRY B. LEAK, a subject of the Queen of GreatBritain, residing at Chatham, in the Province of Ontario and Dominion ofCanada, have invented certain new and useful Improvements in NeelcYokes;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to neck-yokes; and its object is to provide asimple and improved yoke-ring which shall possess advantages in point ofinexpensiveness, durability, and general efficiency.

In the drawings, Figure 1 is a perspective view of a neekyoke embodyingmy improvements. Fig. 2 is a cross-section of the same. Fig. 3 is atransverse cross section taken through the ring. Fig. 4 is a detailperspective view of the plate.

Corresponding parts in the figures are denoted by the same letters ofreference.

Referring to the drawings, A designates the bar or yoke, which may be ofany suitable eonstruction, provided at its center with a circumferentialgrooved portion, a, forming shoulders a.

B designates the yokering, which comprises a single plate formed ofannealed or soft steel, (thus insuring strength and flexibility,) andbent up to form a retaining eye orloop, G, and a top and bottom wing, DE, respectively. The loop G'is formed at the center of the springplate,and is sprung over the grooved portion a and retained in positionthereon by the shoulders a. The top and bottom wings, D E, are formed ofthe end portions of the spring-plate and project forwardly from thefront edges of the central loop. The wings of the plate are providedwith the usual central eye or perforation, d 6, respectively, and havetheir outer edges of circular form, preferably approximating a heartshape, as illustrated in the drawings. By thus forming the ring-plate ofa single plate ofannealed or soft steel bent up as described, cheapnessin manufacture is effected and great durability-and strength socured. r

F designates the leather, which is secured between the wings D E, andhas its outer edge,f, extending to and corresponding with the contour ofthe outer edge of the wings ofthe plate.

The inner edge, f", of the leather is extended, and projects from theinner edge of the wings of the plate to prevent the plate from contactwith the pole. In themanufacture of my improved neck-yoke I prefer touse Spanish sole or harness leather, as may be best adapted, and theleather is provided with the usual central eye, f. The leather issecured in posi tion and the plates retained together by means of anannular series of screws, G, passing through perforations g in one ofthe plates and through corresponding perforations, g, in the leather,and entering screw threaded or tapped perforations g in the other wing.It is obvious that in lieu of these screws rivets may be employed, asillustrated at H, Fig. 3.

I claim as my invention- The herein-described improved yoke-ring bent upin a single piece from a spring-plate of annealed or soft steel andadapted to be sprung over the yoke, said spring-plate eonr prisingintegrally a central loop and the fiat top and bottom wings projectingfrom the front edges of the loop and provided with the circumferentialseries of registering perforations, the leather filling projecting tothe outer edges of the wings of the plate and having the projectinginner edge, f and the annular series of securing-screws, substantiallyas and for the purpose set forth. I

In testimony whereof I affiX my signature in presence of two witnesses.

HEIIRY B. LEAK.
